Got the snapshot loading system working with the +3e. I’ve achieved this by copying the .Z80 files onto a 3.5″ disk formatted for the Spectrum.
I’ve finally made the 8bit IDE interface for the Spectrum +3, and it worked first time. I will try and copy over some .SNA and .Z80 snapshots over to it later. I’ve also added a 3.5″ floppy drive so I can easily transfer files from the PC.
